MACHINE FORATTACHING METAL CLIPS TO CARD-BOARD BOXES SPECIFICATION forming part of Letters Patent No. 416,908, dated December 10, 1889.

Application filed Tune 25, 1887. Serial N0.24Z,436.

To aZZ whom it may concern.-

Be it known that I, JACOB GEIGER, of Stuttgart, in .the Empire of Germany, have invented certain new and useful Improvements in Machines for Attaching Metal Clips to Card-Board Boxes, (for which I have obtained Letters Patent in Germany, No. 39,528, dated June 8, 1887, and in Great Britain, No. 322, dated January 8, 1887,) of which the following is a specification.

The object of my invention is to provide a new and improved machine for fastening toothed metal clips on the corners of cardboard, pasteboard, and the like boxes, for the purpose of holding the sides of the boxes together.

In the accompanyingdrawings, Figure 1 is a plan View of the card-board blank used in making the box. Fig. 2is a perspective view of the box. Fig. 3 is a face view of the metal clip. Fig. 4 is a similar view of the same bent. Fig. 5 is a face view of another shape of the clip. Fig. 6 is an end view of my improved machine for fastening metal clips on the corners of boxes, the jaws being lowered and closed. Fig. 7 I is a cross-sectional view on line 7 7 of Fig. 8, the jaws being lowered and closed. Fig. 8 is a side view. Fig. 9 is a horizontal sectional view on line 9 9 of Fig. 8. Fig. 10 is a detail cross-sectional View of parts also on line 7 7 of Fig. 8, showing the jaws raised and a clip and sides of a box in the machine. Fig. 11 is a detail cross-sectional View of part of the machine, showing the jaws lowered and closed.

Similar letters of reference indicate corresponding parts. I

The sheet-metal clips 0, Figs. 3, l, and 5, are provided with teethS, projecting from the side edges, and said clips are bent rectangularly on the longitudinal axis. The sides of the box are provided along theedges with the slots 19', through which the teeth of the clips can be passed, and then said teeth must be doubled over or clinched on the inside of the box, and this is accomplised by means of my improved machine.

In the bottom part 'of the frame A the shaft o is mounted eccentrically in the end (ModeL) Patented in England January 8, 1887, No. 322, and in Germany Juu disks 8 s, of which the former is provider with the weighted handle-arm q, said disks being mounted to turn in suitable recesses in the ends of the frame" A. A screw z is passed through the disk .9 into the end of the shaft 4:, whereby said disk is connected with the shaft 1:. The shaft 11 may also be connected with the 'disk by aprojection '0, which enters a hole in the center of the disk. The

eccentricshaft is surrounded by the two semicylindrical sections 0' and r, fixed toshort sleeves r loose onthe shaft 1), and provided with upwardly-projecting arms R, on the upper ends of which the jaws t t are fixed, the lower edges of which are beveled to fit .against the trough or V shaped top W of the frame A. The screws .7 serve to hold the jaws it to the upwardly-projecting arms R, and

the stop-pins y y serve to prevent the jaws t if being swung too far from each other. spring U is interposed between the arms R, as shown in Fig. 10, and serves to press the jaws t if from each other.

The operation is as follows: The parts being in the position shown in Fig. 6, the jaws t t are closed, and to open them the handlelever q is swung down in the direction of its arrow, the disks 8 s turning in their recesses in the end of the frame. As the disks are turned, the'sha-ft o is raised and turned in such a manner as to move the arms R R upward, whereby the jaws t t are raised and at the same time moved from each other, as shown in Fig. 10, so as to permit of placing the sides a of the box and the clip 0 upon the trough or V shaped top of the frame A. The handle-lever q is then swung back into the vertical position, whereby the screw 2 is moved downward and the shafto is turned in I such manner as to move the arms R R and the jaws 2ft downward. The bottom beveled edges of the jaws t 25 act on the prongs or teeth S S of the clips 0 and bend them over, as shown in Fig. 11.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a machine forfasteningtoothed metal clips on card-board boxes, the combination of a frame having a V-shaped top and provided with circular recesses, oscillating disks within said recesses, a shaft connected at its opposite ends eccentrically to said disks, arms hinged to said shaft, jaws attached to said 5 arms, and means for actuating said disks.

2. In a machine forfastening toothed metal clips on cardboard boxes, the combination of a frame having a V-shaped top and provided with circular recesses, oscillating disks within 10 said recesses, a shaft connected at its opposite ends eccentrically to said disks, arms hinged to said shaft, jaws at ached to said arms, a spring for spreading said arms, and means for actuating said disks.

In testimony that I claim the foregoing as'i5 my invention, I have signed my name in presence of two subscribing Witnesses.
